Task Description (Required)

the road-core need to provide a configuration file to start the service: https://github.com/road-core/service/blob/main/README.md#configuration

see run with container:
https://github.com/road-core/service/blob/main/README.md#optionally-run-with-podman

it may also need to configure:
https://github.com/road-core/service/blob/main/README.md#optionally-run-inside-an-openshift-environment

some configurations, i.e. db info & credentials, llm server info & credentials will be set in RHDH plugin configuration. and will need to be pass in to the container when start&run the sidecar container

this issue is to investigate how to get this done. to start with, we have already got the llm server configuration,
for example: https://github.com/redhat-developer/rhdh-plugins/blob/76cbf51130b5a0a2a04d7889b0375600c436b6e1/workspaces/lightspeed/app-config.yaml#L81-L85

in rcsconfig, the llm server configuration expect:   https://github.com/road-core/service/blob/3ea924f4945c0677e3ba8576161b37fb14b15075/examples/rcsconfig.yaml#L17-L23

we can investigate pass in rhdh configuration as an extra configuration file to road-core container. and handle the configuration conversion inside road-core service

there is a config-editor being demoed (starting from 53:00), and some script/functions may be reuseable:
